Black Rock Falls is located at the edge of a glacier mountain range, just on the edge of the sea. Warm ocean currents give the beach a more tropical feel, while the mountains nearby create a different environment.
My (current) plan is to create a medieval scene around the falls, followed by a pirate hideout amid the medieval ruins. We'll see...

That's a lot of work! I like those waves coming in as well as all the water work and details. The whole MOC is so nice to me, because everthing looks so well thought out.
Each area has character, good build!
